The extension-type belt conveyor is mainly used for the crossheading transportation on the comprehensive mechanized mining surface, meanwhile, which is still suitable for the crossheading transportation and roadway construction transportation on the general mining surface. When the above-mentioned conveyor is used for the crossheading transportation, the scraper machine shall be provided on its afterbody to connect with the transport machine on the working surface; During the roadway construction transportation, the tape transferring machine will be provided to connect with the roadheader on its afterbody.

Structure Principle:

1. Machine head  2. Tape accumulator  3. Movable roller rack  4. Redirection cylinder rack  5. Traction winch  6. Steel wire rope  7. Traction steel rope  8. Guide cylinder rack  9. Tail  10. Redirection cylinder

Performance Features:

1. The tape accumulator can prolong or shorten the machine to effectively enhance the crossheading transportation capacity and speed up the backstopping and tunneling progress.

2. The movable machine applies the fast detachable bracket which has no bolt for connection, therefore, which has the following advantages, such as, simple structure, convenient assembly and disassembly, low labor intensity and short operation period.

3. The tape tensioning device which is installed on the machine shall be tensioned in the large stroke by the electric winch.
